Specification of Letters Patent.

Patented sept. 26, '1905.

Application iled February 13 1905. Serial No. 245,494.

rTo all whom it may concern,.- v

'Be it known that I, JOHN SHELTON, la citizen of the United States, and a resident of Denver, Colorado, have invented certain new and useful Improvements in Dump-Cars, of-

` the body-bolster upon an enlarged scale.

Fig. 5 is a cross-section through the bodybolster and door. Fig. 6 is a detail elevation of the gearing. Fig. 7 is a plan View of the dumping-lever latch, the dumping-lever being shown in section. Fig. 8 is a perspective of the latch. Fig. 9 is a perspective of one of the crank-arms. Fig. 10 is a perspective of one ofthe door-closing arms.

My present dump-car is animprovement or modification of the dump-car shown in my Patent No. 754,351, dated March 8, 1904.

Referring to/the drawings in detail, the truss-struts 11 extend downwardly from the truss-blocks 12 and are supported by the trussrods 13. The outer sills 15 and 16 and the inner sills 17 and 18 rest upon the truss-blocks 12, and the body-holsters 19 rest upon the sills 15, 16, 17, and 18. The-body-bolsters consistl of center portions 20, having fiat lower faces to rest upon -the sills, the arm portions 21 and 22 extending outwardly from lthe central portions and the attaching-plates 23 and 24 extending outwardly from the arms,y the upper faces of the central portions and the arms 22 being A-shaped in cross-section and the whole bolster being cast hollow, as shown in Fig. 5.

The side pieces 25 and'26 rest'upon and are attached to the plates 23 and 24. The A-shaped bottom 27 is mounted with its edges resting upon the sills 15 and 16. Hinge-plates 28 and 29 are secured to the upper faces of the sills 15 and 16. The hinge-plates 30 and 31 are connected to the plates 28 and 29, and the doors 32 and 33 are secured to the plates 28 and 29, and the doors 32 and 33 are secured to the plates and 3l, said plates 30 and 31 extendl ing entirely across the doors and beyond the doors -to form teeth 34 and 35, said doors swinging upwardly against the arms 21 and 22 and against the lower faces of the sills 25 and 26. The truss-blocks 12 extend beyond the sills 15 and 16 to form stops 36 and 37 to limit the fall of the doors 321 and 33. Shafts 38 l and 39 are rotatably mounted through the sills 15 and 17 andj18 and 16, respectively, and arms 40 and 41 extend outwardly from the 'ends of the shafts atva'ngles of substantially forty-five degrees, there being rollers 42 and 43 upon the outer ends of the arms to engage the doors 30 and 31, so that as the shafts 38 and 39 are rotated the doors are raised to their closed positions. Crank-arms 44 and 45 are fixed upon the inner ends of the shafts 38 and 39, said crank-arms being normally be-A low horizontal positions vand extending from 'the shafts inthe same direction as the arms 40 and 41.

A windlass 46 is mounted under the floor 27 above the body-bolsters- 19, and chains or cables 47 are attached to the windlass, wound upon the windlass, and extend downwardly and are'connected to thel links 48, said links l connecting thevouter ends of the arms 44 Vand 45, so that .when the windlass .is rotated the shafts 38 and 39 are operated to close the doors.l 'A gear 49 is fixed upon one end of the windlass 46, and a pawl 50 is mounted in position to engage the gear and hold it against the winding strain. A pinion 51 is mounted upon a trunnion 52 and meshes with the gear 49, lA gear 53 is integral with or attached to the pinion 52, and a pinion 54, mounted upon the trunnion 55, meshes with the gear 53. A hand-wheel 56 is attached to the gear 54, so that when the hand-wheel is operated the windlass 46 is operated.

Latching-levers 57 and 58 are pivotally mounted in substantially vertical positions upon the outer faces of the side pieces 25 and 26, there being hooks 59 and 60 upon thelower ends of said levers to engage and latch with the teeth 34 and 35 to hold the doors in their IOO IIO

when the hand-levers are operated in the other direction the doors are latehed in their closed positions.

A housing-plate 66 is attached to the side of the car near the upper end of each of the handlevers, and a second housing-plate 67 is mounted outside of the plate 66, the ends of the plate 67 being offset to form the opening' 68, in which the hand-lever operates. A hinge-plate 69 is secured to the outer faeeof` the plate 67 near its center, said plate being mounted upon a pivot '70, so that the plate will'turn edgewise. A second plate 71 is hinged to the plate 69, and a keeper 72 extends from the edge of the plate 7l over the upper edge of the plate 67 and downwardly into the opening 68 to hold the hand-lever 63 to hold the doors latehed and closed. When it is desired to release the doors, the keeper 72 is elevated out of engagement with the bar 67 and turned outwardly on its hinge, so as to allow the lever 63 to swing freely in the opening' 68.

The car-bottom is open on each side of the center throughout its length, so that the contents of the car may be dumped readily by releasing the hand-levers.

I claim-- l. In a dump-car: supporting-sills; bodyholsters mounted on top of the sills; and doors hinged in positionto swing upwardly against the body-bolsters. y

2. In a dump-car: transverse truss-blocks; supporting-sills upon the truss-blocks; bodybolsters upon the supporting-sills; side pieces upon the outer ends of the body-bolsters; and doors hinged in position to swing upwardly against the body-bolsters and side pieces.

3. In a dump-car: transverse truss-blocks; supporting-sills upon the truss-blocks; bodyholsters, doors hinged in position to swing upwardly against the bod y-bolsters; and stops to limit the downward swing of the doors.

4. In a dump-car: supporting-sills; bodybolsters upon the supporting-sills; an A- shaped bottom above the centers ot' the bodyholsters; doors hinged in position to swing upwardly against the body-bolsters; a windlass; shafts mounted transversely oi the sills; cranks upon the inner ends of the shafts and connected to the windlass; and arms upon the outer ends of the shafts to close the doors when the shafts are rotated by the operation of the windlass.

5. In a dump-car: body-holsters suitably mounted; doors hinged in position to swing upwardly against the body-holsters; a windlass; means whereby the windlass closes the doors; a hand-wheel; anda train of gearing between the hand-wheel and the windlass.

6. In a dump-ear: body-holsters suitably mounted; doors hinged in position to swing upwardly against the body-bolsters; teeth upon the doors; latches upon the ear-body to engage the teeth and hold the doors closed; levers for operating the latches; and means of locking the levers and holding the latches closed.

In testimony whereof I have signed my naine to this specification in presence of two subseribing witnesses.
